I took a photo that I wanted to send to someone using Messages (would be an iMessage if that matters)
Trouble is, this photo I took has the 'send' icon greyed out (the bottom LHS in photos app)
ALL other photos are okay, just this one has the send icon greyed out.
I JUST realised this photo also has the 'Edit' action greyed out too.
